I changed the description and added other test cases.

an example of such a board would be

board = [
  [1,2,3,4,5,6,7,8,9],
  [2,3,4,5,6,7,8,9,1],
  [3,4,5,6,7,8,9,1,2],
  [4,5,6,7,8,9,1,2,3],
  [5,6,7,8,9,1,2,3,4],
  [6,7,8,9,1,2,3,4,5],
  [7,8,9,1,2,3,4,5,6],
  [8,9,1,2,3,4,5,6,7],
  [9,1,2,3,4,5,6,7,8]
]
